God's word can come to pass instantly or gradually. But it does not fall to the ground or return unfulfilled.Isaiah 55:11. God releases the word from the heaven, it is your responsibility to engage and enforce it on the earth. How then do you enforce the word of God concerning you to be fulfilled? first of all you must REMEMBER THE WORD(that is why you must write it down), then you must pray the word, you must sow seeds as regards the word and you must keep declaring the word. If it looks as if God's word has failed, DON'T GIVE UP, FOLLOW THE PROCESS AGAIN; REMEMBER THE WORD, PRAY THE WORD, SEED THE WORD AND THEN KEEP SPEAKING THE WORD. GOD IS TOO FAITHFUL TO FAIL.
